In the week a waitress was fired for bedding Orlando Bloom, his ex Katy Perry has boasted she’s having “amazing” sex.

The 32-year-old singer performed at London’s Water Rats in front of a tiny crowd of 90 people on Thursday night, reminiscing about her debut performance in the UK at the same venue nine years ago.

Speaking about her audience growing up too, she told the crowd: “If you’re not having great sex yet, in your thirties it’s going to be AMAZING.

“I can’t speak for those of you in your forties but I’m sure it’s better… it’s fun, consensual and intimate.”

The singer recently released her innuendo-ridden single Bon Appétit and – in case anyone hadn’t quite picked up on what she was alluding to with her lyrics – Katy confirmed: “That’s what Bon Appétit is about, loving that beautiful thing. Just accepting it, now it’s so much fun.

“I used to be able not to hug people, it was really sad. Now I just want to hug everyone.”

Katy – whose new album Witness comes out on June 9 – split from actor Bloom in March, after dating for almost a year.

Orlando, 40, slept with a waitress at London’s Chiltern Firehouse hotel, who was subsequently sacked. In her twenties, Katy married lothario Russell Brand and dated John Mayer.

Also at the gig, Katy revealed she’s been off the booze since January, although earlier in the night she pulled pints for new Capital breakfast show host Roman Kemp, as she celebrated his new role at the radio station.

Earlier this week, Katy said she would happily end her feud with Taylor Swift – who her new single, Swish Swish, is not so subtly about – saying: “Honestly, she started it and it’s time for her to finish it. I’m ready for that BS to be done.”
